Application October 2 Claims.

The present invention relates to butter cutting machines and embodies,more specifically, an improved cutting machine whereby the manipulationof the butter is reduced to a minimum and the machine elements greatlysimplified and reduced in number. It is a matter of common knowledgethat the water content of butter is greatly reduced when the butter ismanipulated, as when it is forced through dies or Shapers underpressure. The corresponding loss in weight is highly objectionable andit is desirable to form suitable prints of the butter with a minimumamount of pressure an-d manipulation thereof.

With the foregoing in view, an object of the invention'is to provide abutter cutting and forming machine, the parts whereof are simple inconstruction and operation, the number of parts being reduced to aminimum.

A further object of the invention yis to provide a machine of the abovecharacter, wherein the `cutter is cut and formed in a minimum number ofoperations, the pressure being applied to the butter in such fashionthat the same is readily shaped and ready to be cut in a singleoperation.

Further objects, not specifically numerated above, will be apparent asthe invention is described in greater detail in connection with theaccompanying drawings, wherein:

Figure 1 is a view in side elevation, partly brokken away and insection, showing a butter cuting machine constructed in accordance withthe present invention.

Figure 2 is a plan view of in Figure 1.

Figure 3 is a detail view in section, taken on line 33 of Figure 1, andlooking in the direction of the arrows, this View showing the spout ofthe shaping device.

Figure 4 is a view in section, taken on line 14-4 of Figure 2, andlooking in the direction of the arrows.

Figure 5 is a view in section, taken on line 5-5 of Figure 2, andlooking in the direction of the arrows.

45- Figure 6 is a View in isometric projection showling a modified formof spout for the mould.

Referring to the above drawings, the frame of a butter cutting machineis shown at 1, having a platform 2 upon which an electric motor 3 ismounted. This motor drives a shaft 4 which is V`preferably journaled ina housing 5, carried on platform 2, and a worm 6 is keyed to the shaft4.

Housing 5 is formed with a cover i and journals a shaft 8 upon which aworm wheel 9 is secured,

'this worm wheel being indicated in dot and dash the machine shown linesin Figure 1. Shaft 8 is journaled at its other end in a Astandard 10which is preferably carried by the platform 2 and mounts crank armcured, this shaft carrying a journaled thereon.

Mounted upon journaled upon a parallel side members 1 shaft 14 is theframe 1 of Between these crank arms a shaft 12 is selink 13 which is60-l the machine and a lever formed of 5 and transverse mem-` bers 16.The lever has extensions 17 which carry 65 a shaft 18. A counterweight19 is journaled upon the shaft to balance hereinafter.

the mechanism described The machine is formed with a bed 2O upon which atable 21 is mounted cal standards 22.

which is shown as formed as erally in the shap Upon the termediate theends thereof is a butter by means of vertibed 20 and inmold 23 one pieceand gene of a reversed L. The vertical portion 24 of the mold receives ahead 25 75- which is restricted by `links 26, secured to the shaft 18.Movement of the head thus takes place in a vertical plane between thepositions indicated in full lines and in in Figure 1. The vertical poris formed with a flange 24 jacent end of the table 21 rests.

of the mold 23 is 95 2, the orifice of which may be varied by means ofthe structure shown in Figure 3. This tending top and which are receivedwithin th structure includes rearwardly eX- bottom walls 33 and sidewalls 34 e end of the spout.

Wing headed screws 35 secure the spout to the horizontal portion 31 ofthe mold and the cross section of the butter issuing from the spout maybe varied by means of an adjusting screw 36. This screw engages one sideof the spout and 10aA flexes the same inwardly to p ermit the crosssection of the butter to be reduced. By withdrawing the screw 36, thespring cent side of the spout restores normal position against the sieffect of the adjathe same to its de of the mold, thus v enabling anadjustment to be made with facility. As shown in Figure 3, it ispreferred that the inner surface of the end of the horizontal portion 31be recessed as at 37 to enable the side and top and bottom walls 34 and33, respectively, to lie flush with the inner surface of the mold. If itis desired to cut the issuing butter into a plurality of layers, one ormore horizontal wires 33 may be stretched across the spout 32, asclearly shown in Figure 3, thus severing the butter into such layers.

The bed of the machine 20 also journals a which receive the butter andfacilitate its movement through a cutting frame 40. The cutting frameincludes spaced parallel side members 4l having a plurality of recesses42 and 43. The recesses 43 slope rearwardly and upwardly to receivewires 44 which are carried upon a yoke frame 45, having an extension 46which is journaled at 47 upon the bed structure of the machine. Yokemember 45 is formed with parallel jaws 48 between which the wires 44 areconnected, a handle 49 being provided to facilitate movement of thewires across the cutting frame. The normal position of repose of theframe is as shown in Figure 5 in which position the wires 44 lie in therecesses 43. When the frame is moved to the left, as Viewed in Figure 5,the wires pass between rollers 39 and are received within the recesses42. During this movement the butter lying within the cutting frame isthus severed transversely into a plurality of sections. From the cuttingframe, the butter moves out upon a receiving table 50, from which it iswrapped or treated in any desired fashion.

As shown in Figure 6, the spout 32 may be replaced by spouts havingapertures of any desired form, a spout 5l being shown as havingcylindrical apertures 52 for forming roll butter.

plurality of rollers 39 formed in any desired shape and size, but littlemanipulation thereof being effected and a minimum of pressure exertedthereon. The moving parts of the mechanism are few in number andeffectively counterbalanced to afford a smoothly operating machine. Byforming the mold as a single piece, the machine is greatly simplifiedand the manipulation of the butter is reduced to a minimum.

While the invention has been described with specific reference to theaccompanying drawings, it is not to be limited, save as defined in theappended claims.

I claim as my invention:

1. In a butter treating machine, a mold comprising a continuous unbrokenchannel having vertical and horizontal portions connected by a bend, thesaid channel being of uniform cross sectional size throughout thevertical portion and having an opening in one side thereof, said channeldiminishing in size gradually from the bend to the outer end of thehorizontal portion, means in said vertical portion for exerting pressureupon butter within said channel, said means having a cutter connectedthereto, whereby upon each pressure exerting operation a slab of butterof predetermined size is cut.

2. In a butter treating machine, a mold comprising a continuous unbrokenchannel having vertical and horizontal portions connected by a bend,said vertical portion having a feed opening in one side thereof, thesaid channel being of uniform cross sectional size throughout thevertical portion and diminishing in size gradually from the bend to thehorizontal portion, a head mounted for reciprocation in said verticalportion and adapted to move past said opening, a table beside saidvertical mold portion and adjacent said feed opening, an arm connectedto said head, and a cutter carried by said arm and disposed above saidtable, whereby movements of said head will cause said cutter to movetoward or away from said table.
